前期准备：
- MYSQL数据库表
CREATE TABLE `tbl_employee` (`id` int(11) NOT NULL AUTO_INCREMENT,`last_name` varchar(50) COLLATE utf8_bin DEFAULT NULL,`email` varchar(50) COLLATE utf8_bin DEFAULT NULL,`gender` char(1) COLLATE utf8_bin DEFAULT NULL,`age` int(11) DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
测试数据
INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('Tom','tom@atguigu.com',1,22);
INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('Jerry','jerry@atguigu.com',0,25);
INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('Black','black@atguigu.com',1,30);
INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('White','white@atguigu.com',0,35)
- user
CREATE TABLE `user` (`id` bigint(20) NOT NULL COMMENT '主键ID',`name` varchar(30) COLLATE utf8_bin DEFAULT NULL COMMENT '姓名',`age` int(11) DEFAULT NULL COMMENT '年龄',`email` varchar(50) COLLATE utf8_bin DEFAULT NULL COMMENT '邮箱',PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
测试数据
DELETE FROM user;INSERT INTO user (id, name, age, email) VALUES
(1, 'Jone', 18, 'test1@baomidou.com'),
(2, 'Jack', 20, 'test2@baomidou.com'),
(3, 'Tom', 28, 'test3@baomidou.com'),
(4, 'Sandy', 21, 'test4@baomidou.com'),
(5, 'Billie', 24, 'test5@baomidou.com');
看图操作，一路下一步
搭建SpringBoot基础环境完成！！！

}
2.2. ORACLE代码生成部分

# Mysql数据库
spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://127.0.0.1:3306/mp?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=CTTusername: rootpassword: root# Logger Config
logging:level:com.gblfy.mybatisplus.generator: debug
4. 启动类加@MapperScan注解
package com.gblfy.mybatisplus.generator;import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
@MapperScan("com.gblfy.mybatisplus.generator.emp.mapper")
public class MybatisPlusGeneratorApplication {public static void main(String[] args) {SpringApplication.run(MybatisPlusGeneratorApplication.class, args);}
}
5. 在controller层写个测试方法：
package com.gblfy.mybatisplus.generator.emp.controller;import com.gblfy.mybatisplus.generator.common.BaseController;
import com.gblfy.mybatisplus.generator.emp.entity.TblEmployee;
import com.gblfy.mybatisplus.generator.emp.service.ITblEmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;import java.util.List;/*** <p>* 前端控制器* </p>** @author gblfy* @since 2019-07-13*/
@Controller
@RequestMapping("/emp/tbl-employee")
public class TblEmployeeController extends BaseController {@Autowiredprivate ITblEmployeeService employeeService;@RequestMapping("")@ResponseBodypublic List<TblEmployee> list() {List<TblEmployee> list = employeeService.list();return list;}
}
6. 浏览器验证
http://localhost:8080/emp/tbl-employee
7. 多模块适配Mybatisplus代码生成 之SpringBoot适配MYSQL和ORACLE
多模块适配只是目录有所他调整而已
